Detailed Description

Illustrative embodiments of the present application include, but are not limited to, a wireless screen projection method, an electronic device, and a computer-readable storage medium.

Embodiments of the present application will now be described with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present application. As can be known to those skilled in the art, with the development of technology and the emergence of new scenes, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

As described in the foregoing background, currently, when a screen is projected wirelessly, there are usually multiple large-screen devices in the same network, and a user needs to manually operate a target large-screen device and an electronic device to establish a screen-projecting connection between the electronic device and the target large-screen device. Specifically, the user needs to manually turn on the target large-screen device into the screen projection mode, and manually input the screen projection code displayed on the target large-screen device in the electronic device. The electronic equipment can start to project the screen to the target large-screen equipment after receiving the screen projecting code input by the user. The screen projection process is complex to operate, the screen projection operation automation degree is low, and the screen projection experience of a user is poor.

For example, fig. 1 shows a scene diagram of a conventional screen projection. As shown in fig. 1, the conventional screen projection scenario includes an electronic device, i.e., a computer 100, two large-screen devices, i.e., a television 200-1 and a television 200-2, and a server 300, where the server 300 is a server corresponding to an office application installed on the computer 100, and the office application (i.e., a first application) can be used for screen projection.

The computer 100, the television 200-1 and the television 200-2 are in the same network, wherein the television 200-1 is a target large-screen device selected by a user. To complete the screen-casting of the computer 100 on the television 200-1, the user first starts the screen-casting mode on the television 200-1 and inputs the screen-casting code on the television 200-1 in the office application.

For example, FIG. 2 shows a schematic view of a scenario in which a user enters a screen-cast code on a television 200-1 in an office application. As shown in FIG. 2, a user enters a screen-cast code on a television 200-1 in an office application: 6688-8866. After the computer 100 detects that the user inputs the screen projection code on the television 200-1 in the office application, the computer 100 sends the screen projection code to the server 300, the server 300 searches the equipment information of the television 200-1 based on the screen projection code, the equipment information comprises the network address of the television 200-1, the network address of the television 200-1 is used for the computer 100 to find the television 200-1, and sends a wireless screen projection instruction to the television 200-1, and the searched equipment information of the television 200-1 is sent to the computer 100. The computer 100 sends a wireless screen projection instruction to the television 200-1 based on the equipment information of the television 200-1, and is connected with the television 200-1 to complete screen projection. Therefore, the computer 100 can complete screen projection after detecting the screen projection code input by the user, the screen projection operation is complex, the screen projection operation automation degree is low, and the screen projection experience of the user is poor.

In order to solve the above technical problem, an embodiment of the present application provides a wireless screen projection method, in which a user does not need to manually input a screen projection code of a target large-screen device in an electronic device, and the electronic device may also be automatically connected to the target large-screen device. Specifically, in the present solution, a plurality of beacon devices may be respectively arranged in a room where each large-screen device is located. The electronic device may receive the wireless signal transmitted by each beacon device and send the signal strength of the received plurality of wireless signals to the server. And determining one room with the largest sum of the signal strengths of the wireless signals transmitted by all the beacon devices in the room by the server, and indicating the device information of the large-screen device in the room to the electronic device. The electronic device can take the large-screen device as a target large-screen device and send a screen projection instruction to the large-screen device.

In the above scheme, the device information may include a network address, where the network address is used for the electronic device to find the target large-screen device determined by the server from the plurality of large-screen devices. The network Address may be an Internet Protocol (IP) Address, and the IP Address is a unique Address allocated to each device on the Internet. Due to the unique address, the user can select the needed target large-screen device from the large-screen devices efficiently and conveniently based on the IP address of the large-screen device when operating on the networked electronic device.

In the above scheme, the beacon device may be a wireless signal positioning beacon, such as a bluetooth beacon device. When a wireless signal positioning beacon is installed at a certain place in a preset space range (in each room), the wireless signal positioning beacon can create a signal area, broadcast signals are broadcast, and when a user carries an electronic device to enter the signal area, the position relation between the electronic device and the preset space range can be determined based on the strength of the received signals.

In the scheme, before the electronic device and the target large-screen device are connected in a screen projection manner, the server obtains the target large-screen device (for example, the large-screen device in the room where the electronic device is located) for screen projection based on the strength of the wireless signals transmitted by the beacon devices in the plurality of rooms near the position of the electronic device, and then indicates the target large-screen device as the screen projection device to the electronic device. Therefore, the electronic equipment can be automatically connected with the target large-screen device in a screen projection mode based on the equipment information of the target large-screen device. The operation that a user needs to manually input a screen projection code for triggering the electronic equipment to be connected with the target large-screen device in a screen projection mode in the electronic equipment before the electronic equipment is connected with the target large-screen device in the screen projection mode is omitted, and the manual operation part is omitted. The screen projection process is simple, the screen projection is intelligent, and the screen projection experience of a user is good.

For example, fig. 3 illustrates an application scenario diagram of a wireless screen projection method according to some embodiments of the present application. As shown in fig. 3, the scene includes an electronic device, i.e., the computer 100, two large-screen devices, i.e., the television 200-1 and the television 200-2, and a server 300, where the server 300 is a server corresponding to an office application installed on the computer 100, and the office application can be used for screen projection.

The computer 100, the television 200-1 and the television 200-2 are in the same network. Wherein, the television 200-1 is a target large screen device selected by a user. Each large screen device corresponds to each room one to one. For example, as shown in Table 1, there is a television 200-1 in room A and a television 200-2 in room B. One or more beacon devices are also provided in each room, for example, as shown in table 2, 4 beacon devices 400 are provided in each of the four corners of room a (401, 402, 403, 404), and 4 beacon devices 500 are provided in each of the four corners of room B (501, 502, 503, 504).

TABLE 1

TABLE 2

In response to a user's screen-casting operation on the application, the computer 100 may collect signals transmitted by surrounding signal devices in order to complete the automatic screen-casting of the computer 100 on the television 200-1. For example, suppose that the computer 100 can collect the signal strengths of 4 beacon devices 400 (401, 402, 403, 404) and the signal strengths of 4 beacon devices 500 (501, 502, 503, 504). The computer 100 may send the acquired signal strength of the beacon device to the server 300. Then, the server 300 may calculate the total signal strength of room a (e.g. 2+ 3= 10) and room B (e.g. 2+1+3+1= 7), where the total signal strength of one room is equal to the sum of the signal strengths of the beacon devices disposed in the room received by the computer 100. Since the total signal strength of the room a is greater than that of the room B, the server 300 may transmit the device information of the tv 200-1 in the room a to the computer 100. The computer 100 receives the device information of the television 200-1 transmitted by the server 300 and transmits a screen projection instruction to the television 200-1. Then, the television 200-1 is connected to the computer 100 and performs screen projection, and the television 200-1 displays the screen projection content of the computer 100.

For example, the electronic device in the embodiment of the present application may be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a Personal Digital Assistant (PDA), or the like. The large-screen device in the embodiment of the application can be a television, a projector, a tablet computer, a notebook computer, a desktop computer and the like.

The power management module 230 may include a built-in power circuit installed inside the tv 200, or may be a power interface installed outside the tv 200 to provide an external power source in the tv 200.

The television 200 may implement display functions via the GPU, the display screen 283, and the application processor, etc. The GPU is a microprocessor for image processing, coupled to a display screen 283 and an application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 210 may include one or more GPUs that execute program instructions to generate or alter display information. A part of the description of the display 283 can refer to the related contents of the above embodiments, and is not repeated herein.

In some embodiments, the display screen 283 may be used to receive image signals output by the processor 210 (e.g., CPU or GPU) and display video content, images, and menu manipulation interfaces.

The video content may be content from broadcast television. The video content may also be content from various broadcast signals received via wired or wireless communication protocols.

The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type.

The camera 284 may be used to capture external environment images. The camera 284 may also be used to capture user interaction gestures for the television 200 to interact with the user. For example, in a motion sensing game scenario, the television 200 may capture various body movements (i.e., interactive gestures) made by the user with the camera 284; the television 200 (e.g., processor 210) may then recognize and respond to these gesture actions to present a different game interface to the user. The camera 284 may also be applied to multiple scenes, such as a multi-screen conference, a video call, and the like of the television 200, and provides an image capturing function for the television 200 in these scenes, which is not described herein again in this embodiment of the present application.

The wireless communication function of the television 200 may be realized by an antenna and the wireless communication module 250, and the like. The wireless communication module 250 may provide solutions including wireless communication such as WLAN (e.g., wi-Fi network), bluetooth, frequency Modulation (FM), near Field Communication (NFC), infrared, and the like, which are applied to the television 200. For example: the wireless communication module 250 may include at least one of a Wi-Fi chip, a bluetooth communication protocol chip, a wired ethernet communication protocol chip, or other network communication protocol chip or a near field communication protocol chip, and an infrared receiver. In the embodiment of the present application, the television 200 can access a wireless network by using the wireless communication module 250, and the wireless network is the same as the wireless network accessed by the computer 100. In this way, the television 200 can display the screen-projecting content of the computer 100 on the basis of the access state of the wireless network after receiving the screen-projecting command sent by the computer 100.

The wireless communication module 250 may be one or more devices integrating at least one communication processing module.

In some embodiments, the antenna of television 200 and wireless communication module 250 are coupled such that television 200 may communicate with networks and other smart devices through wireless communication techniques.

The wireless communication module 250 may also support the tv 200 to receive a control signal from a control device (such as a remote controller or a mobile phone). In some embodiments, a user inputs a user command through a control device such as a remote control or a mobile phone, and the control device may transmit a corresponding control signal to the television 200. The wireless communication module 250 may receive the control signal in response to which other devices of the television 200 respond.

Television 200 may implement audio functions via audio module 260, speaker 260A, microphone 260C, audio interface 260B, and application processor, among other things. Such as music playing, recording, etc.

The audio module 260 is used for decompressing and decoding an externally input audio signal, and performing noise reduction, digital-to-analog conversion, amplification processing, and the like to obtain an audio signal that can be played in the speaker 260A. The audio module 260 is further configured to perform noise reduction processing, analog-to-digital conversion, and other processing on the sound signal collected by the microphone 260C to obtain an audio signal that can be output. In some embodiments, the audio module 260 may be disposed in the processor 210, such as the audio module 260 may be the audio processor mentioned in the above embodiments. Alternatively, some functional modules of the audio module 260 may be disposed in the processor 210.

Besides the speaker 260A carried by the tv 200 itself, the sound signal output by the audio module 260 can also be output to an external device (such as a sound box) through the audio interface 260B for playing. Alternatively, the sound signal output by the audio module 260 may also be transmitted to an external device (e.g., a bluetooth speaker) through the wireless communication module 250 for playing.

Microphone 260C may be used to capture sound signals (e.g., user's sound signals, ambient noise, etc.) around television 200. For example, microphone 260C may capture voice commands for a user to control television 200. The microphone 260C may also collect ambient noise for the tv 200 to recognize the current ambient scene, and may also be used for the tv 200 to adaptively reduce the ambient noise. The television 200 may be provided with a plurality of microphones 260C. One or more microphones 260C disposed on the television 200 may implement directional sound pickup functionality, etc.

The embodiment of the application provides a wireless screen projection method, which can be applied to electronic equipment (such as a computer 100) with the hardware structure, large-screen equipment (such as a television 200) and a server. The server is an application server of the first application, and the first application is installed in the computer 100. The server stores first association information and second association information, wherein the first association relationship comprises a corresponding relationship between a room number and equipment information of a television, and the second association information comprises a corresponding relationship between the room number and an identifier of a beacon device. The roles of the first associated information and the second associated information will be specifically explained below.

FIG. 6 is a schematic diagram illustrating an interaction flow of a computer, multiple televisions, and a server according to some embodiments of the present application. As shown in fig. 6, the wireless screen projection method provided in the embodiment of the present application may include the following steps:

601: the computer 100 and the televisions 200 access the same network.

It can be understood that, at present, when the screen projection function is used, it is necessary to ensure that the tv 200 and the computer 100 are in the same lan, and the tv 200 must be turned on and cannot be turned off when the screen is projected, because once the tv 200 is turned off, the screen is no longer displayed on the tv 200.

602: a beacon device located in a room in which multiple televisions 200 are located transmits a first wireless signal.

As described in the above embodiments, one or more beacon devices are provided in each room. The one or more beacon devices are configured to emit a signal such that the computer 100 can collect the signal and recommend a screen projection device for the computer 100 based on the total intensity of the signal emitted by the beacon devices in each room.

Illustratively, the beacon device may be a bluetooth device, and the first wireless signal may be a bluetooth signal. After each beacon device is powered on, the first wireless signal can be transmitted. The transmission of the first wireless signal is not affected by the screen-shooting operation of the user on the computer 100, and the first wireless signal can be transmitted as long as the beacon device is powered on. For example, the beacon device may periodically transmit the first wireless signal. It should be noted that the transmission power of the respective beacon devices in each room to transmit the first wireless signal should be the same. In this way, the total signal strength of the wireless signal transmitted by the beacon device in each room can be used to determine which room the user and the computer 100 are in, and the screen projection device can be recommended for the computer 100 accurately.

In some embodiments, the number of beacon devices provided in each room may be the same. Thus, the strength of the signal strength transmitted by the signal devices in each room received by the computer 100 is only affected by the distance between the computer 100 and each room, and is not affected by the number of beacon devices in each room. When the total signal intensity of each room is compared, it can be accurately determined which room the user and the computer 100 are located in, and the screen projection device can be accurately recommended for the computer 100.

In other embodiments, the arrangement of beacon devices in each room may be the same. I.e., the number and arrangement of beacon devices in each room is consistent. Thus, the strength of the signal strength transmitted by the signal device in each room received by the computer 100 is only affected by the distance between the computer 100 and each room, and is not affected by the number and arrangement of the beacon devices in each room. When the total signal intensity of each room is compared, it can be accurately determined which room the user and the computer 100 are located in, and the screen projection device can be accurately recommended for the computer 100.

For example, in general, rooms are square, and in order to fully utilize the free corners of each room, four beacon devices of each room may be respectively disposed in the four corners of the room. As shown in fig. 3, from the viewpoint on the current screen, 4 beacon devices 400 (401, 402, 403, 404) of room a are respectively disposed at four corners of room a, and 4 beacon devices 500 (501, 502, 503, 504) of room B are respectively disposed at four corners of room B. Specifically, the beacon device 401 and the beacon device 501 are both located at the upper left corner of the center position of each room; beacon device 402 and beacon device 502 are both in the upper right corner of the central location of the respective rooms; beacon device 403 and beacon device 503 are both in the lower left corner of the central location of the respective rooms; beacon device 404 and beacon device 504 are both in the lower right corner of the central location of the respective rooms. The beacon devices of room a are arranged in the same manner as the beacon devices of room B.

The number and arrangement of beacon devices in each room described above does not constitute a limitation on the number and arrangement of beacon devices in each room in the present application. In addition, the number and arrangement of the beacon devices in each room may be the same, regardless of whether the size of the room is equal, and the arrangement may be: and a plurality of beacon devices are uniformly arranged at equal distances on a circumference formed by taking the center position of each room as the center of a circle and taking the preset length as the radius. Fig. 7 shows a schematic layout of beacon devices in rooms a and B. As shown in fig. 7, the center position of room a is O1, and the center position of room B is O2. In the room a, four beacon devices are uniformly arranged at equal distances on a circumference formed by taking the center position O1 as a circle center and a preset length d1 as a radius: beacon device 401, beacon device 402, beacon device 403, and beacon device 404. Four beacon devices are uniformly arranged at equal distances on a circumference formed by taking the center position O2 as the center of a circle and a preset length d2 as the radius in the room B: beacon device 501, beacon device 502, beacon device 503, and beacon device 504. The lengths of the preset length d1 and the preset length d2 may be equal or unequal.

In other embodiments, the respective beacon devices disposed in each room are located at the same distance from the center location of the corresponding room.

For example, the number of the beacon devices in each room is four, the four beacon devices in each room are respectively arranged on the diagonal of each room, and the distances between the respective beacon devices in each room and the central position of each room are the same. As shown in fig. 3, the beacon device 401, the beacon device 402, the beacon device 403, and the beacon device 404 are equidistant from the center position of the room a. Beacon device 501, beacon device 502, beacon device 503, and beacon device 504 are equidistant from the center location of room B.

As another example, fig. 7 shows a schematic layout of beacon devices in rooms a and B. As shown in fig. 7, the center position of room a is O1, and the center position of room B is O2. Four beacon devices are uniformly arranged at equal distances on a circumference formed by taking the center position O1 as the center of a circle and a preset length d1 as the radius in the room a: beacon device 401, beacon device 402, beacon device 403, and beacon device 404. Four beacon devices are uniformly arranged at equal distances on a circumference formed by taking the center position O2 as the center of a circle and a preset length d2 as the radius in the room B: beacon device 501, beacon device 502, beacon device 503, and beacon device 504.

603: the computer 100 receives a screen-casting operation of the first application by the user, and acquires a plurality of first wireless signals transmitted by part or all of the beacon devices in the rooms where the plurality of televisions 200 are located in response to the screen-casting operation of the first application by the user.

The first application may be an office application on the computer 100, and the operation interface of the office application on the computer 100 includes a screen-projection icon, and the screen-projection operation may be a click operation of a cursor on the screen-projection icon. For example, fig. 8 shows a scene schematic diagram of a screen-casting operation of an office application by a user, as shown in fig. 8, an operation interface of the office application includes a screen-casting icon a, and the screen-casting operation may be an operation of clicking the screen-casting icon a by a cursor.

It should be understood that there may be multiple rooms within a certain range of locations of computer 100, each room having one or more beacon devices disposed therein. The beacon devices in each room are transmitting first wireless signals. The distance between the computer 100 and each of the beacon devices is different, the obstacles in the middle are different, and the computer 100 may not receive the wireless signals transmitted by some beacon devices because the computer 100 is far away from the beacon devices, or the obstacles prevent the computer 100 from receiving the wireless signals transmitted by some beacon devices. Therefore, the computer 100 can acquire the first wireless signals transmitted by a part of the beacon devices, but cannot acquire the first wireless signals transmitted by another part of the beacon devices. Therefore, the plurality of first wireless signals collected by the computer 100 may be transmitted by some or all of the beacon devices disposed in the rooms where the plurality of televisions are located.

The computer 100 sends 604 a first message to the server 300, the first message including signal strengths of the plurality of first wireless signals.

605: the server 300 receives the first message, and calculates the sum of the signal strengths of the first wireless signals transmitted by all beacon devices in the room where each television is located according to the identification of the beacon device transmitting each first wireless signal, and by combining the first association information and the second association information.

The first association information may include: device information of each television 200 of the plurality of televisions 200 and a room number of a room in which the corresponding television 200 is located. For example, the first association information may be as shown in table 1. Wherein each television 200 is located in a room having one or more beacon devices. For example, as shown in fig. 3, four beacon devices are provided in room a, and four beacon devices are also provided in room B.

The second association information may include: the room number of the room in which each television 200 is located and the identification of the beacon device disposed in the corresponding room. For example, the second association information is shown in table 2.

It should be noted that the total signal strength of a room is equal to the sum of the signal strengths of the beacon devices installed in the room and received by the computer 100. The server 300 may determine the rooms to which the beacon devices belong based on the identifiers of the beacon devices transmitting each first wireless signal from the second association information, and add the signal strengths of the first wireless signals of the beacon devices belonging to each room to obtain the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in each room. Then, the server 300 searches for the device information of the television corresponding to the room number from the first related information based on the room number.

For example, as shown in fig. 3, it is assumed that the computer 100 can collect the signal strengths of 4 beacon devices 400 (401, 402, 403, 404) and the signal strengths of 4 beacon devices 500 (501, 502, 503, 504). The computer 100 may send the acquired signal strength of the beacon device to the server 300. The server 300 may determine, based on the identifications of the 4 beacon devices 400 (401, 402, 403, 404), that the beacon devices belonging to room a are beacon devices 401 to 404 from table 1 carrying the second association information described above. Server 300 adds the signal strengths of the four beacon devices 401 to 404 to obtain the total signal strength (e.g., 2+ 3= 10) of the room. Then, the server 300 can determine the device information of the television 200-1 in the room a from the table 2 carrying the above-described first association information based on the room number of the room a.

The server 300 sends 606 a second message to the computer 100. The second message includes device information of the first television. The first television is the one of the plurality of televisions 200 that has the greatest sum of the signal strengths of the first wireless signals transmitted by all beacon devices in the room in which it is located.

607: the computer 100 receives the second message.

608: the computer 100 sends a screen projection instruction to the first television in response to the second message.

The first tv is a tv with the largest sum of signal strengths of the first wireless signals transmitted by all beacon devices in the room of the plurality of tvs 200, and the tv can be used as a target tv for screen projection, so that the computer 100 sends a screen projection instruction to the first tv in response to the second message.

609: the first television receives the screen projection instruction and displays the screen projection content of the computer 100.

In this scheme, the server 300 may automatically determine a target room meeting a preset signal strength condition according to the wireless signals transmitted by the beacon devices in the multiple rooms, and indicate the device information of the television in the room to the computer 100, so that the computer 100 may automatically use the television as the target television and send a screen projection instruction to the television. Thus, the operation of manually inputting the screen projection code of the target television in the computer 100 by the user is saved, and the manual operation is saved. The screen projection process is simple, the screen projection is intelligent, and the screen projection experience of a user is good.

In addition to the above embodiments, in some embodiments, there may be two cases:

the first condition is as follows: the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room where the user is located may be smaller than the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the next room due to the influence of the location where the user holds the electronic device. For this case, the second message may include information about large-screen devices (such as the first large-screen device and the second large-screen device) in which the sum of the signal strengths of the first wireless signals transmitted by all beacon devices in the room is arranged in the first two digits. The electronic device may display the room number of the room in which the two large-screen devices are located, with the user selecting the large-screen device that is ultimately projected. Therefore, the screen projection accuracy can be improved, and the screen projection experience of a user can be improved.

And a second condition: it may happen that the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room where the user is located is equal to the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the next room. For this case, the second message may include information about the large-screen devices (e.g., the first large-screen device and the second large-screen device) with the first rank, which is the sum of the signal strengths of the first wireless signals transmitted by all beacon devices in all rooms. The electronic device may display the room number of the room in which the two large-screen devices are located, with the user selecting the large-screen device that is ultimately projected. Therefore, the screen projection accuracy can be improved, and the screen projection experience of a user can be improved.

Specifically, in this embodiment, the second message may include not only the device information of the first large-screen device, but also the device information of the second large-screen device. The first large-screen device and the second large-screen device are located in different rooms. The second message also includes the room number of the room in which the first large-screen device is located and the room number of the room in which the second large-screen device is located.

From the above embodiment, it can be seen that: the first large-screen device is a large-screen device of the plurality of large-screen devices, the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room is the largest.

In the second case, the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the second large-screen device is located is the same as the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the first large-screen device is located. That is, the first large-screen device and the second large-screen device are arranged in parallel with the large-screen device with the largest sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room (referred to as the large-screen device with the largest signal strength).

In the first case, the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the second large-screen device is located is smaller than the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the first large-screen device is located, but is greater than the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which any one of the large-screen devices except the first large-screen device is located. That is, the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the second large-screen device is located is second only than the sum of the signal strengths of the first wireless signals transmitted by all the beacon devices in the room in which the first large-screen device is located.

In this embodiment, the scheme of the embodiment of the present application is described by taking an electronic device as a computer 100 and a large-screen device as a television as an example. The 607 may include 607a1-607b1.

607a1: the computer 100 responds to the second message and displays the first interface. The first interface comprises the room number of the room where the first television is located and the room number of the room where the second television is located.

The room number of the room where the first television is located and the room number of the room where the second television is located, which are included in the first interface, can be used for determining the final screen projection television according to the user's will, so that the screen projection accuracy is improved.

Specifically, in some embodiments, the first interface may include an option button of the room number of the room in which the first television is located and an option button of the room number of the room in which the second television is located, where the option button of the room number of the room in which the first television is located is used to trigger the computer 100 to send a screen projection instruction to the first television, and the option button of the room number of the room in which the second television is located is used to trigger the computer 100 to send a screen projection instruction to the second television. For example, fig. 9 is a schematic diagram illustrating a scenario in which a user selects a plurality of televisions recommended by the computer 100 for screen projection. As shown in fig. 9, the operation interface of the office application includes a prompt option box B, which includes prompt information for asking the user to select a device desired to be projected, and an option button: the television option button B1 for room No. 1 and the television option button B2 for room No. 2.

607b1: the computer 100 sends a screen projection instruction to the first television in response to the selection operation of the user on the room number of the room in which the first television is located in the first interface.

In some embodiments, if the first interface includes an option button of the room number of the room in which the first television is located and an option button of the room number of the room in which the second television is located, the user may click the option button of the room number of the room in which the first television is located or the option button of the room number of the room in which the second television is located, so as to complete the user's selection operation on the room number of the room in which the target television (the first television or the second television) is located in the first interface, so as to trigger the computer 100 to send the screen projection instruction to the target television. For example, as shown in fig. 9, the selection operation may be the user clicking on the tv option button B1 for room No. 1 or clicking on the tv option button B2 for room No. 2.

In this scenario, the computer 100 may display the room numbers of the two rooms in which the first televisions are located, and the user selects the first television that is finally projected. Therefore, the screen projection accuracy can be improved, and the screen projection experience of a user can be improved.

The above is the case for one large screen device per room. In other embodiments, there may be situations where there are two large screen devices in a room. For this case, the second message may include information about two large-screen devices (e.g., the first large-screen device and the third large-screen device) arranged in the first place, where the sum of the signal strengths of the first wireless signals transmitted by all beacon devices in the room is located. The electronic device may display the two large-screen devices of the room, with the user selecting the large-screen device that is ultimately projected. Therefore, the electronic equipment can determine the large-screen equipment for projecting the screen according to the wish of the user, the accuracy of projecting the screen can be improved, and the screen projecting experience of the user can be improved.

In this embodiment, the scheme of the embodiment of the present application is described by taking an electronic device as a computer 100 and a large-screen device as a television as an example. The 607 may include 607a2-607b2.

607a2: the computer 100 responds to the second message and displays a second interface. The second interface comprises the identification of the first television and the identification of the third television.

The second interface comprises the identification of the first television and the identification of the third television, so that a user can determine the final screen projection television according to own will, and the screen projection accuracy is improved. Specifically, in some embodiments, the second interface may include an identified option button of the first television and an identified option button of the third television, where the identified option button of the first television is used to trigger the computer 100 to send a screen-casting instruction to the first television, and the identified option button of the third television is used to trigger the computer 100 to send a screen-casting instruction to the third television.

The identity of the first television and the identity of the third television may be user-defined names that may be used to distinguish between the different televisions.

607b2: the computer 100 sends a screen-casting instruction to the first television in response to the user's selection operation of the identifier of the first television in the second interface.

In some embodiments, if the first interface includes an option button identified by the first television and an option button identified by the third television, the user may click the option button identified by the first television to complete the user's selection operation on the target television (the first television or the third television), and then trigger the computer 100 to send a screen projection instruction to the target television.

In this scheme, after receiving the second message, the computer 100 may display a second interface including the identifier of the first television and the identifier of the third television, and the user selects the first television for screen projection in the second interface. In this way, the computer 100 can determine the first television for screen projection according to the wish of the user, which not only can improve the accuracy of screen projection, but also can improve the screen projection experience of the user.
